Abstract: PURPOSE:To suppress the spreading of the contents of impurities in order to obtain a semiconductor element capable of being micronized by impressing a magnetic field on the impurities introduced into a semiconductor layer so as to control diffusion of the impurities and form an impurity-containing layer. CONSTITUTION:When a magnetic field H is impressed during heat treatment for activation of boron ions B<-> for forming a semiconductor element, boron ions B<-> perform a rotary movement having a fixed radius so as not to be diffused into the inside of a substrate 10. Accordingly, boron ions B<-> are confined inside the source.drain regions 28a and 28b. Further, since boron ions B<-> of a channel part 16 perform similarly a rotary movement, diffusion to the substrate 10 is suppressed so as to hold the depth of the channel part shallow. Thereby, diffusion of impurities to the inside of the substrate can be suppressed so as to allow the element to be micronized.
